Exhibit I <br /> Page 1 <br /> EXHIBIT I <br /> SOILS INFORMATION <br /> Per Rule 6.4.9—Soils Information:(1)In consultation with the Soil Conservation Service or other qualified person, <br /> the Operator/Applicant shall indicate on a map (in Exhibit C) or by a statement, the general type, thickness, and <br /> distribution of soil over the affected land Such description will address suitability of topsoil(or other material)for <br /> establishment and maintenance of plant growth. If necessary, at its discretion, the Board may require additional <br /> information on soils or other growth media to be stockpiled and used in revegetation. <br /> Refer to Exhibit C-4: Affected Area-Soils Mapping for a depiction of the soil units present within the Kersey <br /> Mine Site.The following supplemental information is provided and should be considered in conjunction with the <br /> map-depicted data. <br /> In addition to the foregoing, a summary of the mapped soils is also provided in Table I-1: Summary of Mapped <br /> Soils Data,below. <br /> The proposed Kersey Mine consists mainly of rangeland occupied by numerous active and inactive oil and gas wells <br /> and associated well pads and related infrastructure. It is not anticipated that"refuse"materials will be encountered. <br /> To the extent any such materials may be encountered,CSC will ensure that the disposition of any such materials will <br /> be accomplished in a manner consistent with all applicable laws,regulations, and ordinances. <br /> The eolian sand deposit to be mined is the result of wind erosion(deflation),transport,and re-deposition, largely via <br /> saltation and/or creep processes. The Kersey Mine sand deposit is on the northeast flank of the Denver Basin(also <br /> referred to as the Denver-Julesburg,or D-J Basin),a tectonic basin located in northeast Colorado, southeast <br /> Wyoming,and southwest Nebraska.The D-J Basin is bounded on the west by the Colorado Front Range(Dechesne, <br /> M.and others;2011). Areas of the D-J Basin that are adjacent to the Rocky Mountain Front Range have been <br /> divided into two sub-basins: (a)the southern sub-basin is considered the Denver Basin;and, (b)the northern sub- <br /> basin is considered the Cheyenne Basin.The Denver and Cheyenne Basins are defined by the extent of the Laramie <br /> Formation and are separated by a structural feature called the Greeley Arch. The basin's underlying sedimentary <br /> rocks are comprised of sedimentary units that dip generally to the south and southwest at about 50 to 100 ft.per <br /> mile. The immediate underlying strata are comprised of the upper and lower units of the Laramie Formation, <br /> respectively,with the uppermost part consisting of 250 to 600 ft. of shale, siltstone,claystone, occasional sandstone, <br /> and minor coal. Below this,the lower unit is comprised of an approximately 100 to 300 ft.thick zone of sandstone, <br /> shale,and coal.(Kirkham and Ludwig; 1979). <br /> Per the USDA soils data,the Valent sand that is to be mined is of neutral acidity.Mining activity will be carried out <br /> in such materials;no bedrock or other types of material are anticipated to be encountered.Thus,no acid-generating <br /> or toxic materials are anticipated to be present within the mined materials. <br /> Colorado Sand Company II, LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
